FEEDING MECHANISM.

Specification of Letters Patent. 7

Patented May 23, 1916.

Original application .filed April 4, 1910, Serial No. 553.330. Divided and. this application filed August 17, 1910. Serial No. 577,625.

To all whom it may concern Be it known that I, CLIFTON F. LEATHER- BEE, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have inventedcertain new and useful Improvements in Feeding Mechanism, of which the following is a specification.

The present invention relates to machines for applying liquids and fluids of various kinds to the surfaces of materials of various contours, and more especially to the pr0- vision of an improved formof apparatus which may be used to subject lengths of flooring, strips of molding, cross arms, and like strips or lengths of moving material to the application of paint, stain, varnish, creosote and other finishing or preservative substances, or to coat them with insulation, and simultaneously to remove any excess of the applied substance and polish and finish the treated article.

The principal objects of my present invention are the provision of a machine characterized as above noted, which is adapted to treat the material speedily andinexpensively and to apply the substance used with great facility and thoroughness to all the surfaces of material of irregular contour, such .as wainscoting, electric wiring conduits and the like; to provide feed regulating means whereby, when desirable, a minimum amount of the treating substance may be supplied to the applying means; to provide means whereby any excess of material fed to the applying means may be removed from the machine and returned to the supply tank and used again to avoid loss, and to provide improved means for'removingthe treated material from the machine and keeping it exposed to the atmosphere for acertain period of time to the end that it may dry and be more readily handled, as well as certain further objects hereinafter more fully to appear. a

The present application is directed particularly to the features of the feeding mechanism, the drying apparatus, the coat ing apparatus, and the conveyer forming the subject matter of my co-pending application Serial No. 553,330, filed April 4, 1910, of

which the present application is a division,

and of other divisions of said application.

TIn the attainment of the objects above set.

to be disclosed below, Ihave provided a con-o struction, a preferred embodiment of which is illustrated in the accompanying drawings 7 wherein- Figure l'is a side elevational view, partly in section, illustrating the feeding fluid applymg and polishing mechanism; Fig. 2 is arplan view of the machine shown in Fig. 1; Fig. 3 is asectional view taken on the line III-III of Fig. 2; Figs. 4 and 5 respectively are plan and sectional views of a modified detail of construction.

Referring now more particularly to Figs. 1 to 3,.it will be noted that in carrying out my invention I make use of a framing 20, preferably of cast metal provided at each end with supports 20, which may be conveniently located adjacent to the end of a planer or other machine for forming flooring, wainscoting and similar products. Inasmuch as I find machines embodying my improvements peculiarly available in connection with the use of quick-drying fluids containing volatile oils, I prefer to have themclosedto the atmosphere in order to avoid the evaporation, using therefor a light cover for the top, (not shown). At the delivery end of the machine, I provide a primary belt convey er'2l longitudinally disposed. with relation thereto for removing the treatedmaterial discharged therefrom and. inalinement with but on a plane below the conveyor 21, a secondary belt conveyer for receiving and delivering such articles.

Inrorder that the increase of cost and loss of time incident to rehandling the material after "leaving the planer, may be saved and to insure .a direct feed of such material through the machine without lateral displacement, it may be fed by the live rolls of the planer; otherwise such feed may be effected by the oppositely disposed live rollsv .23 and 24-driven from the motor 25 through the gearing to be hereinafter described. A

live rolls 31, 32, and 33, 34, adapted to hold it in contact with the brush devices 35, 36, 37 and '38, designed respectively for applying the liquid, for rubbing it in, for wiping any excess from the edges of the materials and for removing any vestiges from the face thereof. r V

On viewing Fig. 1 particularly it will be observed that I'mount in the framing the rotatable brush 35, movable vertically to the end that compensation may be made for wear in service by means of'its suspension in the outer ends of the yoke 40 pivoted in the casing as indicated at 41, 41, one end of which is provided with an adjusting screw 42.

' 54, whereby wear of the. brush may be further compensated for. The fioor of the framing forms a drip pan for the several brushes and a drain pipe 56 continuously opento the tank 46 is provided to convey thereto any excess liquid thatmay perchance fall upon such pan.

'For driving the pump 45, the brush-35, and'the rolls 24, 32 and 34, in unison, to the end that a uniform application of liquid may be had, I mount ;on the shaft of the motor 25 a pulley 60 driving by means of a belt 61 the pulley wheel 62 which is mounted on the shaft 63 carrying the roll 34. The opposite end of the shaft 63 is provided with a gear 65 which by means-of a chain 66 drives the gear 67 mounted on the shaft 68 of-the roll 32.' The shaft 68 carries on the end, (opposite to thatcarrying the gears 67 and 69),, a gear73 driving, by

means of the intermediate gears 74 on a shaft 74 and 75 on the shaft 76,'the gear 75 on the shaft.76 carrying the roll 31. At the end of said shaft 76' is mounted a sprocket wheel 77 driving by means of the chain 78 the pump 45. On the end of the shaft 72 opposite the sprocket 71 is carried a gear 7 9 which through intermediate gears 80 on the shaft 80*, and 81 on the shaft 82 drives'th'e gear 82 on the shaft 83? carrying the roll 23. Upon said shaft 82 is mounted a pinion 83 driving through the chain 84 the sprocket 85 on the shaft 86 carrying the brush 35. J

In order that the upper rolls 23, 30, 31

' I and 33 may be adjusted axially to accommodate materials of differing thicknesses,

and that they may be conveniently removed where desirable, I preferably mount them in the opposing members of pairs of boxes 88, 89, 90 and 91 pivoted to opposite sides of theframing 20, each box being provided at'itsfree end with an adjustable screw de vice 92 having engagement with an extension of the box and inserted in a socket formed in the framing. Springs 92 -92 under a certain degree of compression are mountedupon the said screw device 92 on both sides of said extension in order to compensate for any slight unevennesses in the material.

Inasmuch as I have designed the machine illustrated as an-embodiment of my present invention primarily for the purpose of employing highly volatile treating compound to flooring, the respective sizes of the pulley 77 and 77 by which the pump is driven through the belt 78, should be so proportioned that as closely as possible the pre- .cise amount of liquid that may be taken up by the brush 35 be delivered upon the spreader plate'50, in order to avoid any accumulation upon the drip pan 55 or the rolls; Asa further precaution against spatter-ing of the liquid, or throwing thereof from the brush 35, I provide such brush with a cover 35, open at the top, and supported by the shaft 86 and yoke 40. This is especially desirable since my improved machine'is used with great economy for the treatment offlooring as it issues from the planer, and such locations usually present such paint. As a further guard against accumulation of residual material, I provide the: rolls 30,, 31 and with shields 30 31 andf'33.

Eaclr of the stationary brush devices 36 and 38 is vertically adjustable by means respeetively of the screw devices 95, 96 threaded into a bottom extension of the framing 20, to the end that compensation may be had for any wear of such brushes in service, and each of the brushes 37, 37 is adjustable laterally by the screw members 97, 97 threaded into the sides of the framing 20 and resting at their inner ends in the stop blocks 98, carried upon a plate 99 supported by the angle bars 99, 99, also mounted-in the framing 20, for the purpose of limiting the inward movement of the said brushes 37. For a three-fold purpose, viz., alining the material in its passage through the machine, directing it -betweenthetwo brushes 37, and holding it in contact with the brush 36 (here shown as-smade in three parts carried in a frame '36 Jfor thesakeof convenience in replacement and: in order that unequal wear of the several parts may be cared for without discardingunworn portions), I provide the cooperating spring devices comprising the laterally pressing, oppositely disposed springs 100, 100 adjustably mounted in blocks' 101, 101 carried by the yoke 102, and thedown- Wardly pressing springs 103 in the block 104, provided upon said yoke 102 between the springs 100. 7

Referring now to the alternate arrangement illustrated in Figs. 4 and 5, it will be observed that in this construction, in lieu of the stationary brush 38, I make use of a revolving brush 38 mounted in bearings 105, 105 carried by the arms 106, 106 of the yoke 107 pivoted in the framing 20 as indicated at 108, 108 and adjustable vertically by the screws 109 threaded into the framing as indicated at 110' at each side thereof, sustaining such bearings. The brush 38 is driven from the shaft 63 by means of a pinion 105 connected to the sprocket 106 on the shaft 10 7 carrying such brush, by a chain 108*. In the present device, as in that of Figs. 1 to 3, the roll 33is driven by means of the gears 111' carried on the shaft 63, the intermediate gears 112 and 113 on shafts 112 and 113*, and the gear 114 mounted on the shaft 115 of said roll 33. In the device of Figs. 4 and 5 the roll 34; serves not only as part of the means for sustaining and feeding the material through the machine, but also for the purpose of removing from the brush 38 any liquid that may have accumulated thereon ensuant upon the progress of material through the machine, and over such brush, whereas in the device of Figs. 1 to 3, the roll 34; serves the sole purpose of sustaining and feeding such material.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is the following:
